Render A File Select Input Field

Renders an HTML <input> element of type file, defaulting to the specified value or the specified property of the bean associated with our current form. This tag is only valid when nested inside a form tag body.

As with the corresponding HTML <input> element, the enclosing form element must specify "POST" for the method attribute, and "multipart/form-data" for the enctype attribute. For example: 

 <html:form method="POST" enctype="multipart/form-data"> <html:file property="theFile" /> </html:form>

WARNING: In order to correctly recognize uploaded files, the ActionForm bean associated with this form must include a statement setting the corresponding org.apache.struts.upload.FormFile property to null in the reset() method.

This means that your users will have to re-select any previously selected files when submitting the form. Opera web browser will prompt the user so they have a chance to abort the submit.
